Proactivity state and a cycle action exist, hidden from the keybinding docs and behind a switch nothing sets.
What
Session state gains a proactivity level, initialised to default, and it is passed into tool-use contexts, subagent relaunch payloads and permission-mode resolution. A keybinding action for cycling proactivity exists but is filtered out of the generated keybindings documentation, and the switch that would show the selector defaults to false with nothing in this build setting it, so the UI is unreachable here.
Details
- A
proactivitysystem-reminder type is registered in both reminder sets. - Relaunch payloads carry the proactivity level together with the tool permission context.
